Missing Properties or Exception After Automatic Template Extraction

Environment

Product Version	2018.3.1016
Product	RadGridView for WPF

Description

Missing elements in the UI after a custom template is applied to a Telerik control. Or an error appears after the custom template is applied.

Those issues are observed in some cases when extracting the Style of a Telerik control using Microsoft Blend or the Visual Studio's designer.

Solution

To resolve this, instead of extracting the Style (or the template) using Microsoft Blend or the Visual Studio's designer, use the .xaml files from the UI for WPF installation folder. This is the Themes.Implicit folder. It contains all the Styles of the Telerik controls. Read more about this in the Editing Control Templates article.
